Given an array of numbers, of any length, create a function which counts how many of those numbers pass the following criteria:
- The first and last digits of a number must add to 10.
Examples
endsAddTo10([19, 46, 2098]) ➞ 3
endsAddTo10([33, 44, -55]) ➞ 1
endsAddTo10([]) ➞ 0
Notes
- All items in the array will be numbers.
- Ignore negative signs (see example #2).
- If the number contains only one digit, that digit will be the first and the last digit.
- If given an empty array, return
0.
